The word "cyber-space" was coined through the developments in communication technology and computers. It became possible to experience disembodied space in practice through a new kind of medium. this research aims to clarify the kansei stimulation elements as realistic sensed by users who use 3-dimensional expressions in cyber-space. The research was carried out by preparing 25 samples of computer graphics, and administering 3 questionnaires to 12 examinees. The Principal Ingredient Analysis method was used for its analysis and assessment. As a result of this research, it can be concluded that materials, reflection and shadow have the strongest effect on human beings' senses in cyber-space.

This study suggests the emotion space modeling and emotion inference methods suitable for personalized services based on psychological and emotional models. For personalized emotion space modeling taking into account the subjective disposition based on the empirical assessment of the personal emotions felt by the personalization process of emotion space was used as a decision support tool, the Analytic Hierarchy Process. This confirmed that the special learning to perform personalized emotion space modeling without considering the subjective tendencies. In particular to check the possible reasoning based on fuzzy emotion space modeling and sensitivity for the quantification and vague human emotion to it based on the inherent human sensitivity.

The opportunity provided for design method and strategy of community space for secondary school through the experience of public library and gallery, is the purpose of this paper. Community space is an important issue in school architecture as it seeks to revive the public area in educational building and to renew the open space as a multi-entertainment space. The latest works of school, however, which are evaluated as well reflected the reality of educational patterns, are still deficient in that communicational elements in school are underdeveloped and inadequate. The cases of this paper, which are grown up as entertainment library and multi-purpose cultural space such as Seattle Public Library, Sendai Mediatech, Tate Modem Gallery, and Kunsthaus, are suitable to offer the method of the creation of community space for school. This paper reviews an assessment of its success in community space for school architecture with multi-entertainment-purpose library and cultural space connected open space and concludes with the establishment of design method for future school; extraction of the factors contributing to development of community space in school and proposal of design method; implementation of school renewal with library and gallery plus open space for the creation of identity considering both of study and play.

This research has a significance on providing basic material of landscape ecological planning and open space planning of the future site by selecting Sinseo innovative city area, large residential land development district in rural area, by classifying biotope types and implementing recreational value assessment in the level of area. First of all, as a result of classification of biotope types in research site, total 11 biotope type groups including stream biotope and its subordinate 51 biotope types. Also, as a result of the first value assessment of classified biotopes, there are total 5 types such as vegetation-full natural river, fallow ground in I grade. In addition, it is analyzed that grade II have 18 types, III are 10, IV are 12, the least valuable V are 6. Especially, grassland biotope(GD) was classified into grade II, which is one grade raised, because it is analyzed that it has high value in terms of normal access and availability although it was assessed as grade ill in terms of natural experience quality. Lastly, as a result of the second assessment, special areas for natural experience and recreation(1a, 1b) are 15, areas for natural experience and recreation(2a, 2b, 2c) are 47. Especially, the 52th drawing mark space was grade II in the first assessment but its value grade was upgraded because of its high value in terms of use evidence, size of the area, accessibility with housing area, history and cultural character and so on.

확률론적 수명예측은 파라미터들의 불확실성에 대하여 확률론적인 요소를 적용한다. 따라서 기존의 결정론적 수명해석 기법에 확률론적 기법을 적용하기 위해서는 파손확률을 이용한 위험도 평가가 필요하다. 본 연구에서는 항공기 구조물의 확률론적 위험도평가를 수행하기 위하여 파손확률 추정 모델링 기법을 연구하였다. 이를 위해 파라미터들의 확률론적 불확실성을 효과적으로 반영할 수 있는 베이지안 기법을 이용하여 파손확률을 모델링하고 실험 데이터를 이용하여 검증하였다. 연구결과 베이지안 기반의 파손확률 추정 모델링은 정량적인 파손확률을 계산하고 확률론적 위험도평가를 효과적으로 수행할 수 있음을 입증하였다.

기존의 터널 유지관리 체계는 결함 및 손상부위의 보수 또는 설계기준을 충족하기 위한 보강 등 사고예방적인 안전성 중심의 유지관리방식으로 관리되고 있어 효율적이고 전략적인 유지관리를 실시하는데 한계를 보이고 있다. 현재 국가연구를 통해 터널의 성능저하를 예측, 평가하여 한정된 재정을 효율적으로 투자할 수 있도록 성능중심의 유지관리체계로의 전환을 시도하고 있다. 본 연구에서는 터널시설물을 중심으로 기존의 안전중심의 유지관리 체계에서 구조적 안전은 물론이며, 서비스수준 및 내구성능 등의 성능저하를 고려한 터널시설물의 성능중심 평가체계의 개발을 위하여 성능평가를 위한 평가지표를 도출하고자 한다. 성능중심 평가기법 개발을 위한 평가지표는 문헌자료 분석 및 델파이 설문을 통하여 선정하였으며, 평가지표간의 중요도는 AHP 분석을 통해 산정되었다. 본 연구결과는 터널시설물의 성능중심 유지관리 체계에 적용되어 터널의 유지관리 시 합리적인 의사결정을 지원할 수 있을 것으로 판단된다.

본 연구는 터널굴착 공사에 의한 지반거동을 평가하여, 구조물의 형상, 위치, 굴착공정 변화등의 다양한 조건과 지반/구조물의 상호작용이 고려된 모형실험을 기본으로 수행하였다. 굴착진행 단계에 따른 구조물의 손상 거동 평가시 인접 구조물이 밀집된 도심지 굴착에서는 보다 안전하고 보수적인 평가가 나타나는 각변위와 수평변형율에 의한 손상도표를 활용하는 것이 보다 안전할 것으로 판단된다. 모형실험시 구조물에 발생된 균열의 손상수준을 손상도표에서 평가해 본 결과, 균열손상 수준이 적용된 평가가 각변위와 수평변형율만 적용된 손상수준보다 안전측으로 평가되는 것을 확인할 수 있었다. 그러므로, 각변위와 수평변형율 뿐만 아니라 균열이 고려된 손상평가를 수행하는 것이 보다 바람직할 것으로 판단된다.

The purpose of this study is to present an appropriate approach to urban regeneration by analyzing Gwangju Metropolitan City. For the study, residential area of Asia Culture Complex was analyzed based on GIS. The areas concerned were categorized and looked into by their Situation based on the analysis of urban infrastructure state. However, as the architectural space within a city are limited, and accurate assessment of them is needed. The residential areas have the following characteristics. They become an aging and dilapidating residential and socially underprivileged-concentrated area. It is necessary to set up a direction for a future-oriented planning for the development of these areas. Along with a decreasing population, it is important to improve the urban architecture environment for the elderly in an aging society. The economic growth of a city if necessary for the future. Therefore, the criteria for the assessment is required. And the subsequent setting-up and planning of a future direction for a city is badly needed. After that, an accurate assessment of a city called for. City space allows for various interpretations. As the rich are getting richer and the poor are getting poorer, a wealth is concentrated on one district or an area.

This study investigated elementary students' (grade 4~6) learning progressions for water cycling drawn from iterative assessments using ordered multiple-choice (OMC) items. An assessment system, which consisted of construct map, item design, outcome space, and measurement model, was employed in this study to examine children's learning progressions. At the first stage of the assessment system, a construct map was designed on which children's conceptual understandings from naive to most sophisticated were represented. At the item design stage, 8 OMC items were drawn from the construct map. Each item option of the OMC items was scored from 0 to 3 according to its level of understanding at the stage of outcome space. As a measurement model, Rasch model, a branch of item response theory, was applied to interpreting the outcomes of the OMC items. This cycle of assessment system was furtherly implemented iteratively in order to elaborate on the first version of water cycling learning progression. In conclusion, children's understanding of water cycling could be described in two aspects: water distribution and water movement. We identified children's conjectural developmental pathways about water cycling existed from superficial and naive accounts to more complex and abstract accounts.
